DRAFT-EQUALIZER.

SPEGIFIGATIONYfOrming part of Letters Patent No. 261,355, dated July 18,1882.

Application filed February 13, 1582. (No'modeh) To all whom it mayconcern:

Be it known that I, JEREMIAH O. J oNEs, ot' Whitt, Parker county, Texas,have invented a new and Improved Double-Tree, of which the following isa full, clear, and exact description.

The object of this invention is to provide a double-tree adapted to beused without singletrees, and one which will equalize the draft in caseone horse gets ahead of the other.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of my improved double-tree. Fig. 2 is asectional elevation of the same, taken on theline a: roof Fig. 1; andFig. 3 is a detailed elevation of the front edge of the double-tree.

A represents the double-tree,which is formed with the mortise b in thecenter, and is provided at its ends with the hooks a (1. Upon each sideof the mortise the double-tree is provided with the eyebolts c c, inwhich the ends of the bail B are linked. In the mortise b is placed theguttered pulley D, which is held in place by the pin or bolt f, whichpasses through the double-tree and through the center of the pulley.Upon the pulley is placed the chain H, which is provided with the hooksd d, to which the inside trace-chains of the harness are to be hooked.The bail B is formed in the center with the eye h, in which the clcvisis to be placed when the team is to be attached to any object not havinga tongue. When the team is to be attached to any machine, vehicle, orconveyance having a tongue, the bail B will not be used, but the pin orbolt f will be removed, and the ordinary bolt of the tongue will bepassed through the hammer-strap and through the double-tree, pulley, andtongue.

By this construction it will be seen that the action of the chain Hissuch as to equalize the draft in case one horse is in advance of theother. When the pin or boltfis not used it may be placed through thehole *5 in' the doubletree, where it will be carried, so as to be alwayshandy when needed for use.

The chain H is by preference held in place in the guttered wheel by thepin or bolt h,

which passesthrough the wheel near its edge, as shown clearlyin Figs. 1and 2; but,instead of using this bolt, the chain may be held by asuitable rivet passed through a link of the chain and into the peripheryof the wheel.

Having thus described my invention, I claim asnew and desire to secureby Letters Patent- The combination, with the double-tree A, providedwith the hooks a at its ends, and the bail B, secured to its rear part,of the grooved pulley D, pivoted in a mortise at the center of thelength of said double-tree, and the chain H, provided with hooks (1 atits ends, and seoured at the center of its length in the grooves of thepulley, substantially as herein shown and described, and for the purposeset forth.
